Well that's what I'm looking for.I'm barely through the Guided Tour of McCLIM and some of the examples aren't working well and I have no idea what other toolkits there are and which are good.I would appreciate some experience reports and recommendations.

If you don't mind the spartan look and the lack of its own documentation, you can use ltk. It's quick, no-frills and very easy to use -- not to mention very straightforward if you used Tcl/Tk before. Some Tk functions are not implemented, but it works fairly well if you don't need anything serious. Otherwise, I'd recommend clg as well.

You can use lambda-gtk. The version on site is old and not working on sbcl, but it is trivial to get it working. It offers a complete gtk binding.(the patch to get it working is http://mo3r.nm.ru/lambda-gtk-0.1-sbcl-c ... -asd.patch )Other gtk+ bindings didn't work for me (apart from cells-gtk, which I haven't tried).
